Hard-Coated Broadband Filters

Our first-surface, hard-coat broadband filters employ magnetron sputtered, hard-oxide coatings deposited on Borosilicate Glass and do not utilize any absorbing filter glasses, making them suitable for high temperature applications. They provide a steep transition from a high, peak transmission to OD4 blocking. Available at standard Raman wavelengths: 488, 514, 532, 633, 785nm, as well as other popular wavelengths. We offer three standard sizes, with custom sizes and ring mounting available on request.

Also, be sure to check our surplus stock for other wavelengths and bandwidths.
